Abstract
Treatments that obdurate dentin tubules have been used for reducing dentin hypersensitivity. This study was to determine the effect of a treatment with a slurry of micron sized calcium phosphate on the hydraulic conductance (Lp) of etched dentin discs in vitro. The treatment slurry was prepared by mixing a powder mixture of dicalcium phosphate anhydrous and calcium hydroxide (Ca (OH) 2) with a solution that contained NaF and carboxymethyl cellulose. The mean baseline Lp (in L cm-2 sec 1 H2O cm-1) was 2.07 1.45 (mean S.D.; n = 13, L cm-2 sec 1 H2O cm-1= 10.20 in L cm-1 min-1 Kpa- 1). After one treatment and 3, 5, and 8 days of incubation in a saliva like solution (SLS) the mean relative Lp, presented as % of baseline, were 65 16, 42 27, 36 26, and 33 27 (n = 13), respectively. The Lp values of the baseline and treatment after incubation in the SLS were significantly (pCitation
